[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] like Figure 1 - Figure 4 As shown, a powder conveying system for a 3D printing device includes a conveying structure 1, which includes a soundproof box 11. A feeding trough 14 is fixedly installed on the outer wall of the top of the soundproof box 11, and a drive motor 12 is fixedly installed on the outer wall of the top of the soundproof box 11 and on one side of the feeding trough 14.

[0024] A second drive motor 13 is fixedly installed on the left side of the outer wall of the soundproof box 11. One end of the second drive motor 13, located in the inner cavity of the soundproof box 11, is connected to a drive plate 16. A discharge port 15 is fixedly installed on the outer wall of the bottom of the soundproof box 11.

[0025] It should be noted that in this embodiment, when the powder enters the inside of the feeding trough 14, the first drive motor 12 is started, and the first drive motor 12 drives the stirring rod 144 at the top of the inside of the feeding trough 14 to descend, so that the powder enters the stainless steel filter screen 161 on one side of the drive plate 16 through the inclined guide tube 141. Then the second drive motor 13 is started, and the second drive motor 13 drives the plate 16 to rotate rapidly.

[0026] A stainless steel filter screen 161 is fixedly installed on one side of the outer wall of the drive disc 16. A circular frame 162 is fixedly installed on the outer wall of one end of the stainless steel filter screen 161. An inclined guide tube 141 is fixedly installed on the outer wall of the bottom of the feed trough 14. A rolling groove 1411 is opened at one end of the bottom outer wall of the inclined guide tube 141. A ball bearing 1412 is tumblingly connected to the inner side of the rolling groove 1411. The outer wall of the ball bearing 1412 is tumblingly connected to the outer wall of the inner side of the circular frame 162.

[0027] It needs to be explained that, in this embodiment, when the disc 16 is driven to rotate by the second driving motor 13, the second driving motor 13 drives the powder in the inner side to overturn, and the fine powder is overturned into the inner cavity of the soundproof box 11, and then the powder is collected in the discharging port 15 for discharging. When the stainless steel filter screen 161 rotates, the circular frame 162 installed on the outer wall of one end of the stainless steel filter screen 161 rolls with the ball 1412 on the bottom outer wall of the inclined guide pipe 141, so that the stability of the stainless steel filter screen 161 driving the powder to overturn is ensured.

[0028] The bottom of the inner side of the discharging chute 14 is fixedly installed with a supporting plate 142, one end of the transmission rod 121 driven by the first driving motor 12 is connected with the inner cavity of the supporting plate 142, the outer wall of the inner side of the transmission rod 121 is fixedly installed with a fixed block 143, the outer wall of the inner cavity of the fixed block 143 is fixedly installed with a limiting plate 1431, one end of the transmission rod 121 in the inner cavity of the fixed block 143 is fixedly sleeved with a first bevel gear 1211, the outer wall of the first bevel gear 1211 is engaged with a second bevel gear 1441, the outer wall of the agitating rod 144 is fixedly sleeved with a limiting disc 1442.

[0029] It needs to be explained that, in this embodiment, when the powder is added into the inner part of the discharging chute 14, the first driving motor 12 is started, one end of the transmission rod 121 in the inner cavity of the supporting plate 142 is driven to rotate, the first bevel gear 1211 and the second bevel gear 1441 are engaged in the inner cavity of the fixed block 143, the second bevel gear 1441 drives the agitating rod 144 to rotate, and the top of the agitating rod 144 is driven by the limiting disc 1442 limited by the limiting plate 1431 to agitate the inner cavity of the discharging chute 14, so that the powder is driven to descend to the inclined guide pipe 141.

[0030] The working principle of the utility model is: when the powder is added into the inner part of the discharging chute 14, the first driving motor 12 is started, one end of the transmission rod 121 in the inner cavity of the supporting plate 142 is driven to rotate, the first bevel gear 1211 and the second bevel gear 1441 are engaged in the inner cavity of the fixed block 143, the second bevel gear 1441 drives the agitating rod 144 to rotate, and the top of the agitating rod 144 is driven by the limiting disc 1442 limited by the limiting plate 1431 to agitate the inner cavity of the discharging chute 14, so that the powder is driven to descend to the inclined guide pipe 141,

[0031] Therefore, the powder passes through the inclined conduit 141 into the stainless steel filter screen 161 on one side of the driving disc 16, and then the second driving motor 13 is started to drive the driving disc 16 to rotate rapidly, and when the driving disc 16 is driven to rotate by the second driving motor 13, the powder in the inner side is turned over by the second driving motor 13, the finer powder is turned over into the inner cavity of the soundproof box 11, and then the powder is collected in the discharging effect through the discharge port 15, and at the same time, the stainless steel filter screen 161 rotates, the round frame 162 installed on the outer wall of one end of the stainless steel filter screen 161 rolls with the ball 1412 on the bottom outer wall of the inclined conduit 141, so that the stability of the stainless steel filter screen 161 is ensured when the powder is turned over by the stainless steel filter screen 161.
